Hi,
I have got this expression from Mathematica:
Sqrt[a^2*(Cosh(x))^2*(Sin(y))^2]
I have tried to simplify this expression with Simplify[], but it returns the same result.
I have tried to solve some other expressions and it returned some strange forms.
For example:
I have tried to solve some equation on paper and I've got this:
a*Sqrt[(Cos(x))^2+(Sinh(y))^2]
Then I have tried to solve the same equation with Mathematica and it has returned some long expression containing combinations of double angles.
Does anyone know what to do to get the simplest expression?
Anyway I don't know why Mathematica couldn't simplify an expression as simple as a*Sqrt[(Cos(x))^2+(Sinh(y))^2]
